Hiering,Newark, N. J., assignor to The J. E Mergott Company, Newark, N. J., acorporation of Delaware I Application July 1, 1936, Serial No. 88,346, 4Claims. (cl. 113--116) This invention relates to frames for hand bags,and more particularly to a method of making said frames.

Hand bag frames are generally U-shaped, and

in order to prevent buckling anddistortionat the comers, heretofore,considerable care has been necessary in the bending of the frame. In U.S. Patent No. 1,925,804 granted to me on September 5, 1933, there isdescribed a method of making a frame whereby neat, sharp and solidcorners are produced which are free from open joints, with no puckeringof the metal. That patent applies especially to a channeled frame memberopening upwardly. It is an object of the present invention to provide amethod ofmaking a hand bag frame which is substantially tubular, havinga. lateral opening. In accordance with the invention, a blank isprovided from which the frame is formed. 20 This blank has cut thereintriangular openings and trapezoidal notches in the edge of the blankadjacent the triangular openings. From this blank there is formed asubstantially tubular member which is bent into a U-shaped frame handbag frame from a single sheet of bendable metal, without resorting tospot welding or rivet- 40 ing or the attaching of an additional piece ofmetal to the frame member at the corners thereof. e

A further object is the provision of a novel blank for forming a tubularframe member, which 5 blank consists of a single strip of materialprovided with openings and notches therein to enable it to be bent toprovide neat angled corners.

These and other advantageous objects, which will later appear, areaccomplished by the simple 50 and practical construction and arrangementof parts hereinafter described and exhibited in the accompanyingdrawing, forming part hereof, and in which:

Fig. 6 shows a comer of a. frame member formed in'accordance withmyinvention, and

Fig. .7 isa view showing the obverssideof the corner shown in Fig. 6. I

Referring to the drawing, in Fig. 2 there is shown a metal strip 8 fromwhich the frame members are formed. The strip is provided withtriangular openings 9, and adiacent each opening 9 the edge of the stripis provided with trapezoidal notches I0, thus forming connecting stripll between the openings 9 and the notches HI. After providing the strip8 with ;the openings 9 and notches III, the strip is then bent into asubstantially tubular shape as indicated in Fig. 3, having the edges l2and I3 spaced from each other on the same side of the tubular member.The tubular member is then bent into a U-shape, each corner being formedas shown in Figs. 4 and 5, the connecting strip ll being doubled backupon itself as indicated in Fig. 5 and the corners thus produced havethe appearance shown in Fig. 6.

By means of this method, I am able to produce neat right-angled cornersin a substantially tubular U-shaped hand bag frame member, withoutcracking or buckling of the metal at the corners during the bendingprocess.

The foregoing disclosure is to be regarded as descriptive andillustrative only, and not as restrictive 'or limitative of theinvention, of which obviously an embodiment may be constructed includingmany modifications, without departing from the general scope hereinindicated and denoted in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. The method of making a substantially tubular bag frame member havingan angledcorner from a flat metal strip, comprising providing the stripwith a triangular opening and a trapezoidal notch in the edge of thestrip adjacent said opening forming a. connecting strip between theopening and the notch, then bending the strip into a substantiallytubular shape so that the connecting strip forms a part of a wall of themem-; .ber, then bending the tubular member so that the connecting stripwill be doubled back upon itself to produce a right angled corner.

jacent said notch providing a connecting strip be-.

tween the opening and the notch, the bases of said opening and notchbeing adJacent each other.

4. The method 01 making a cylindrical tubular U-shaped bag frame memberhaving right angular comers, comprising forming trapezoidal notches inthe longitudinal edge of a strip otbendable sheet material, forming atriangular opening in said strip adjacent each notch to provideaconnecting strip, bending the strip into a substantially cylindricaltubular shape, and then bending the tubular shaped strip so that theconnecting strips will be bent back upon themselves and the triangularopenings will be closed toprovide angled corners.
